Hello learned members, I have a small Bulova with Serial number F23355 which appears to be in pristine condition. I have been trying to start it up using Renata 394 with spacer ring but it refuses to start. If I tap the casing with either my finger or more effectively with a plastic screwdriver the second hand moves a few times then stops. If I keep tapping it then it will continue to move but sometimes erratically.

I don't know anything about Accutrons but, from looking at photos of other ones on here, this one looks like it's been tampered with already. It's appears to have an older tin can style transistor in it and the color code bars are missing on the resistor. And it looks like a diode has been put in it on top of the capacitor.
